Answer:
 where 
 denote arc lengths of two circles
Step-by-step explanation:
Let 
 denote arc lengths of two circles, 
 denote corresponding radii and 
 denote the corresponding central angles.
So,
 and 
This implies 
 and 
As each circle has an arc where the measures of the corresponding central angles are the same, 

As radius of one circle is twice the radius of the other circle,


 
        
             
        
        
        
All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18
        
                    
             
        
        
        
Equations don't have minimum or maximum, functions do.
Function y=2n^2+5n-25 has minimum -28.125, has no maximum.
